Chang: OSPF demand circuit is what is required here. In addition,
consider :
no peer neighbor-route - to eliminate ppp host routes
area 33 as a virtual link if R2 has any OSPF areas other than 0, and 33
cost for isdn link.
Lately there have been counterfeit copies claiming to be ECP1 and ECP2 labs
on eBay, some are copies of copies, some contain labs with wrong answers.
All violate the copyright which is held by NetMasterClass, LLC. Recent
auctions have been terminated by eBay for copyright infringement.
Cheers, Fred
